Rhapsody already announced a simliar joint billing agreement with Verizon and now Rhapsody touts that it offers wireless carrier billing to more than half of all mobile phone users in the US.

“In addition to offering value, we have a lot to gain from partnerships like the one with AT&T,” Rhapsody president Jon Irwin said in the blog post. “We’ve always believed in a pursuing a sustainable business that benefits both the people listening to all the great music we offer, and the artists who are creating it. These billing agreements reduce churn on our end and expand the Rhapsody community without giving away music for free, which is important to us.”

Rhapsody is an independent, privately held company, based in downtown Seattle, following its 2010 spinoff from RealNetworks. However, RealNetworks retains a large stake in Rhapsody and reports Rhapsody’s financial results as part of its quarterly regulatory filings.
